Why GEN4?? Ford made a few big changes to the 2024-2025 Raptor 3.5L Ecoboost Engines.  These engines do not have exhaust manifolds and the turbos are bolted directly to the heads. Ford first did this on the 2.7L and 3.0L Ecoboost engines.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOur Industry first Alpha Cats provide ultra high flow while meeting green emission standards.  Factory GEN4 Raptor downpipes are very restrictive because Ford reduces the diameter of their primary cats from 5.5\" to 5\". This reduction in diameter ( -5 square inches of surface area) causes much higher back pressure and EGTs.  With SPD Alpha ultra high flow cats and larger 3\" diameter mandrel bent tubing, you will improve throttle response, mileage and overall performance while reducing turbo lag and exhaust temperatures. Our turbo flanges are CNC laser cut 1\/2\" 304ss flanges and we TIG \u0026amp; MIG weld the downpipes for strength and durability. We designed in a 4\" flex pipe  to absorb shock from engine movement and chassis flex.  Our downpipes do not require custom tuning and can be used as a factory downpipe replacement. Our catalytic convertors are made in the USA and are designed to be used in racing applications.  \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSPD Alpha Cats\u003c\/b\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSPD Alpha Cats are next generation ultra high flow green emissions catalytic convertors and are truly an industry first.  We needed a catalytic convertor that would have high flow and green emissions. Every catalytic convertor that we tested in the industry either had green emissions or high flow but not both.  SPD Alpha Cat is a 500cell catalytic convertor and will out flow our previous 400cell performance cats by +90%. They are extra loaded with Rhodium, which is a platinum based alloy that is required in a catalytic convertor to reduce NOX in the exhaust to meet the new emission standards. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan\u003eOn all SPD Performance 304 stainless catted downpipes, you get:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul type=\"disc\"\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eIncrease in performance\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eImproved turbo spool time\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eBetter fuel mileage\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eDirect turbo bolt-on design\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eNO CEL - Ultra High Flow 500Cell catalytic converters that do not cause check engine lights\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003e304 Stainless Steel 3\" mandrel bent tubing \u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\u003cspan\u003eHigh grade v-band clamp for a solid seal and no leaks\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWe use EPA approved federal catalytic converters but you are responsible to verify that they are legal with your state and county laws.\u003c\/span\u003e\u003c\/p\u003e","brand":"SPD","offers":[{"title":"Default Title","offer_id":51785563177239,"sku":"FDP35FR24SS","price":2245.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5895\/5031\/files\/GEN4DOWN-800x800.jpg?v=1767856691","url":"https:\/\/shopsouthdowngarage.ca\/products\/spd-performance-alpha-catted-downpipes-2024-2025-gen4-ford-3-5l-raptor","provider":"Southdown Garage Shop","version":"1.0","type":"link"}
